I keep getting algae no matter what I do water changes .. Changed gfo and carbon cut down on my lights skimmer is running parameters are perfect ... It's brown and look like slime ... I used chemi clean also in out of options here
CUC is not always the answer to algae problems. Especially if it's red slime. We need to know your parameters, lighting and feeding schedule. 1 question, can you blow it off with a baster? And if so, did it come off in chunks? Pic would help too.
This won't happen
